Brow elevation ratio: a new method of brow analysis.

Area of Science:

• Plastic Surgery
• Ophthalmology
• Medical Imaging

Background:

• Assessing brow position changes after surgery is crucial for evaluating outcomes.
• Existing methods for measuring brow position may lack precision or standardization.
• Endoscopic brow suspension is a common procedure for correcting brow ptosis.

Purpose of the Study:

• To introduce and validate a novel quantitative method for measuring brow position.
• To apply this method to patients undergoing endoscopic brow suspension.
• To establish a reliable metric for assessing surgical outcomes in brow elevation procedures.

Main Methods:

• Retrospective review of patients undergoing endoscopic brow and forehead lift.
• Standardized digital photography for preoperative and postoperative brow position assessment.
• A novel measurement system using the brow elevation ratio (brow height to intercanthal distance).

Main Results:

• Sixteen patients (32 eyebrows) showed statistically significant brow elevation post-surgery.
• Mean brow ratio increased by 17.1% overall, with sustained elevation at follow-up.
• The method demonstrated high reliability and applicability in assessing surgical outcomes.

Conclusions:

• The brow elevation ratio is a valid quantitative tool for assessing outcomes of brow suspension.
• Standard office photography is sufficient for applying this measurement system.
• This method facilitates objective comparison of brow position and surgical results.
